Incompetent Cervix
Tuesday, September 16th, 2008Fortunately, this condition is rare, unless the cervix has been damaged during a previous pregnancy or surgery. When you’re pregnant, the cervix normally remains tightly shut and is sealed with a plug of mucus. This means that your baby is safely held in the womb until labor begins, when the cervix begins to dilate.
Occasionally, though, the cervix begins to open before it should, usually in the third or fourth month-a condition termed cervical incompetence. This allows the amniotic sac containing the baby to sag through into the vagina and rupture, with a sudden loss of amniotic fluid followed by miscarriage. Unfortunately, an incompetent cervix is usually diagnosed only after a Woman has suffered a first miscarriage.
If cervical incompetence is thought to be the cause of previous miscarriage, a soft, nonabsorbable thread will be inserted around your cervix to tighten it. After bed rest in the hospital, you’ll be able to go home, but you’ll need to get plenty of rest during the remainder of your pregnancy. The thread will be cut about seven days before term, and your baby will be delivered vaginally in the normal way.
